Do you have any tips for my flight to Donegal?
We've got the lowdown on how to make your journey a pleasant experience. Follow our tips and you'll be speeding through the airport and having a ball in Donegal in no time at all. What to pack in your hand luggage:

  • The trick to having a stress-free flight experience is to plan ahead. So, let's start with the essentials: passport, travel documents, cash and vital medications. Next, bring on board items that'll help keep you entertained, like some electronic gadgets or a magazine. It's also a wise idea to bring your chargers, a quality neck pillow and a pair of earphones. And of course, don't forget to squeeze in toiletry items like a toothbrush, deodorant and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a sharp object lurking in one of the zippers of your hand luggage. Other banned items include flammable or explosive goods, such as aerosol cans and fuel, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of a plane are no place for a fashion parade. Don comfortable layers and opt for shoes that are flat and easy to take on and off.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-haul flights. Lower your risks by staying hydrated, keeping your ankles and legs moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Donegal?
Being prepared before you arrive at the airport will make your getaway to Donegal quick and painless. Below are some useful tips and tricks for a swift journey past security:

  • Have your boarding pass and ID at hand. They're the first things you'll be asked to present to security.
  • Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Your electronic gadgets like laptops and phones will also need to go on a tray for inspection. Don't worry, you'll be back online soon enough.
  • Want to bring along your favourite cologne? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you're permitted to bring it with you on board.
  • There's a chance you'll be asked to take your shoes off for scanning, so wearing lightweight sneakers is always a wise idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked baggage. They won't be allowed in the cabin.
